What is the lash specification for a manual steering system with a steering wheel diameter of 21 inches?

1. 5 3/4 inches

2. 5 1/4 inches

3. 5 1/2 inches

4. 4 1/2 inches

The correct answer is: 5 1/2 inches

In the context of manual steering systems, lash specification refers to the allowable amount of free play in the steering system, which is crucial for maintaining control and safety while driving. The lash specification is often determined based on the diameter of the steering wheel, as a larger wheel typically allows for more movement before the steering rack or column engages. For a steering wheel with a diameter of 21 inches, the correct lash specification is established at 5 1/2 inches. This measurement indicates the maximum amount of play in the steering wheel before any movement is felt in the wheels themselves. Ensuring that the lash is within this specification is vital for proper steering performance; too much play could lead to a vague steering feel or difficulty in vehicle control. Following the correct specifications contributes to vehicle safety and aids in avoiding premature wear on steering components. Proper understanding and adherence to these specifications are essential for both technicians performing inspections and drivers relying on their vehicle's steering system for handling and stability.
